The test results you have selected are very old and may not represent the current state of Wine.
Selected Test Results (selected in 'Test Results' table below)
The game, mostly. Tested dialogues (both text&speech), slide sequences, gameplay, menus.
What does not
Intro video is scaled badly (wrong size, vertical and horizontal lines). Midi music plays with glitches. Fullscreen mode crashes immediatly after start. Through the game, an error "chain fail" occasionally pops up (just press "ok", it's nothing). Keyboard input might lag
What was not tested
Didn't walk through the whole game yet
To avoid the initial start-up crash, the EXE should be patched.
You should replace it either with Japanese demo EXE (from the game demo which can be found here http://www.hs-crowd.co.jp/crowd/product/lot/bs/bs.html ) or with a localized EXE from a localization pack (like this one http://www.zoneofgames.ru/gamebase/game/746/file/959/ for Russian users). Note that the executable contains most of the game menus, as well as descriptions of items and certain dialogue options, and therefor it all will be translated. The demo EXE also makes impossible to view the gallery or the intro.
Also, if you experience distorted in-game fonts, you should place something like tahoma or verdana or sans-serif in Wine's 'windows\fonts' directory
